Patented Nov. 19, 1907.

Application Sled February 9.1907. Serial No. 356.587.

hereby. declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it pertains to make and use the same. This invention relates to improvements in cushion tires especially adapted for heavy and comparatively slow moving vehicles.

The object of this invention is to provide a tire which will have the strength and durability of a solid tire combined with the flexibility and resiliency of a pneumatic tire.

My invent-i011, therefore, consists in providing, in combination with a Wheel a tire comprising a pneumatic tube and a shoe or casing arranged to inclose said tube and independently supported from the wheel so as to be free to move with the movement of the pneumatic tube without detracting from the 25 I uoyancy thereof.

' My invention also consists in the features of construction and combination of parts as described in the specification, pointed out in the cl aims and illustrated in the accompanydrawings.

ing n the accompanying drawings, Figure 1 shows a wheel equipped with a tire embodying my invention.. Fig. 2 is a section on line 2--2, Fig. 1. ,Fig 3 is a section on line 3**3, Fig. l. Fig. 4 is an enlarged sectional view ofa portion of a tire. Fig. 5 is a section on line 5-5, Fig. 4.

Again referring to the drawings 1 represents the wheel which is provided with the usual rim 2`. Aroundthe rim of the wheel is preferably arranged ,a i metallic band 3, which as sh'own in the drawings is provided with flan es 4 but the flanges may be omitted if desire An endless tube of rubber 5 01' other suitable material adapted to -be inflated by air or other means is mounted on the band 3A and constitutes theA inner member of my-tire. Thel outer member of my tire comprises` ashoe or casing which -is preferably ormedy of metal and is U-sha ed in cross sec tion. The casing is arran to completely inclose, the lpneumatic tu e and the sides thereof'lap over the rim of the wheel. lThis casing consists 'of an annular plate or tread 7. Ati-.one side of the` tread is arranged a side plate 8 which is preferably formed integral with the tread 7 and extends u and laps on the rim of the wheel at one si e.

On the op osite side of the tread is formed an annular ange 9. The removable side of the casing is formed of a series of independent plates 10, which as shown in the draivings are four in number. Each of these plates 10 has a depth equal to the depth of the opposite side plate 8 andis arranged to lit inside of the flange 9. Each plate 10 is made long enough to overlap the ends of the adjacent plates 10 and on the overlappingr end of each plate 10 is formed anear 11, the ears on the overlapping ends of the plates being arranged to coincide with eachother.

On'the side plate 8are also formed earsp'12 Wlnch are arranged to register with geaxjll on the plates 10 when said plates are in their.

proper position. On the rim of the` wheel are formed four pairs of projections or lugs' 15 which are spaced the same distance apart as the ears on the side plates of the shoe. Pins 16 are passed through openings formed in the ears on the-side plates and between the lugs of each pair of lugs and said lu'gsof each pair of lugs are so spaced as t`o permit the pm to have sufficient play to allow for the movement of the shoe or casing corresponding to the compression of the pneus matic tube while at the same time securing the shoe to the rim of the wheel. On each side of the rim of the wheel, vwhere the side plates of the casing overlap the rim, is ar# ranged a packing ring 18 of rubber or any other suitable material. The acking rings 18 are supported in annular games 19 secured to the rim of the wheel. The object of the packing rin s is to prevent dust or other foreign materia' from entering the casing and injuring the pneumatic tube.

- In carrying out my invention itwill readily .be seen that the construction'can be ch ed to a considerable extent without de artmg from the s irit of my invention and do not therefore limit myself to the exact form which I- have shown'.

L1. The combination with a Wheel of a pneumatic tube arran ed on the rim thereof .fand a casing arranger to inclose said pneumatic tube, said casing comprising a bottom o r tread portion, a side portion formed integral therewith, a side portion detachably secured to' said tread portion and consisting ofa number of independent plat-es, ears formed on said detachab e plates and on the integral side'v plate, lugs formedfon the rim of said I ears formed on the detachable side portion .y

Wheel and pins passing throu h said ears and lbetween said lugs, substantia 1y as described and for the purpose se'tforth. vE 2. The eombination With -a Wheel of a pneumatic tube arranged. on the rim thereof' and a easing arranged to inclose said pneu# p v matic tube, said easing comprising va bottom or tread port1on,a side portion lformed inte- 10 gral' at one edge thereof, a fiange'formed integral at, the-opposite edge, a detachabie side l portion arranged'to 'fit Within said ange,'.`

and on the integral side portion, lugs formed v on the rim of said Wheel and pins pas'singfl through said earsand between said-vlugs, substantially as' described.

In testimony whereof, I sign the foregoing specification, in .-the presence 'of two Wit:

nesses. v
